Answer:
The area of the rectangle is defined as
Area = height* width
Area = 20 u^2
This means that any multiplication between two numbers which results in the value 20, can be the either the width or the height.
For example, suppose the width and the height are integers.
The possible combination for the pair of values are
1 & 20
2 & 10
4 & 5
With either number being the height or the width
